vtkExtractSelectedFrustum Class Reference
#include <vtkExtractSelectedFrustum.h>
Detailed Description
Returns the portion of the input dataset that lies within a selection frustum.This class intersects the input DataSet with a frustum and determines which cells and points lie within the frustum. The frustum is defined with a vtkPlanes containing six cutting planes. The output is a DataSet that is either a shallow copy of the input dataset with two new "vtkInsidedness" attribute arrays, or a completely new UnstructuredGrid that contains only the cells and points of the input that are inside the frustum. The PreserveTopology flag controls which occurs. When PreserveTopology is off this filter adds a scalar array called vtkOriginalCellIds that says what input cell produced each output cell. This is an example of a Pedigree ID which helps to trace back results.

Member Function Documentation
| static vtkExtractSelectedFrustum* vtkExtractSelectedFrustum::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkDataObjectAlgorithm.
| virtual const char* vtkExtractSelectedFrustum::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkExtractSelectionBase.
| static int vtkExtractSelectedFrustum::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkExtractSelectionBase.
| virtual int vtkExtractSelectedFrustum::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkExtractSelectionBase.
| void vtkExtractSelectedFrustum::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkExtractSelectionBase.
| unsigned long vtkExtractSelectedFrustum::GetMTime | ( | ) | [virtual] |
Return the MTime taking into account changes to the Frustum
Reimplemented from vtkObject.
| virtual void vtkExtractSelectedFrustum::SetFrustum | ( | vtkPlanes * | ) | [virtual] |
Set the selection frustum. The planes object must contain six planes.
| virtual vtkPlanes* vtkExtractSelectedFrustum::GetFrustum | ( | ) | [virtual] |
Set the selection frustum. The planes object must contain six planes.
| void vtkExtractSelectedFrustum::CreateFrustum | ( | double | vertices[32] | ) |
Given eight vertices, creates a frustum. each pt is x,y,z,1 in the following order near lower left, far lower left near upper left, far upper left near lower right, far lower right near upper right, far upper right
| virtual vtkPoints* vtkExtractSelectedFrustum::GetClipPoints | ( | ) | [virtual] |
Return eight points that define the selection frustum. Valid if create Frustum was used, invalid if SetFrustum was.
